Description
The MAX5969BETB+T is a power management integrated circuit (IC) designed by Analog Devices under the MAXIM brand. It is primarily used for Power-over-Ethernet (PoE) applications, which allow the delivery of electrical power along with data over standard Ethernet cables. The MAX5969BETB+T is a type-2 powered device (PD) interface controller that is compliant with the IEEE 802.3at standard, also known as PoE+. This standard supports higher power delivery compared to the older IEEE 802.3af standard.
Key features of the MAX5969BETB+T include input signature recognition, classification signature generation, and inrush current limiting. It is designed to enable safe operation by providing thermal protection, undervoltage lockout, and overload protection. The device also facilitates flexible powering options with support for both local power and power from the Ethernet cable. The IC is encapsulated in a compact TQFN package, making it suitable for space-constrained applications such as IP cameras, VoIP phones, and wireless access points that require efficient power management and simplified design.
